What are the contraindications for stent surgery for coronary heart disease?

Coronary heart disease is a common disease in life. This disease can cause serious harm to the patient's body, so patients should receive timely treatment. Common treatment methods generally include drug therapy, stent placement, and bypass surgery. Patients can choose the treatment method according to their condition. If the condition is more serious, it is best to perform stent surgery. So what are the contraindications for stent surgery for coronary heart disease?

First, what are the contraindications of stent surgery for coronary heart disease? Stent treatment for coronary heart disease has immediate effects. Many patients believe that once the symptoms of coronary heart disease disappear, the disease is cured. Actually, it is not. The full name of coronary heart disease is coronary atherosclerosis, which means that people with coronary heart disease have all the coronary arteries in their heart narrowed, but the degree of narrowing varies, some are milder and some are more severe. The length of the stent is limited, and it is only used to treat the coronary artery with the most severe narrowing. It is impossible for doctors to place a stent in the entire coronary artery. Stent treatment is only symptomatic treatment, and after the stent is placed, the patient still has to take medication.

Second , there are two purposes of taking medicine. One is to prevent restenosis at the stent, and the other is to prevent the degree of atherosclerosis in other coronary arteries from worsening. After stent placement, it is necessary to take aspirin. While the stent expands the narrowed blood vessels, it also damages the vascular endothelium. The human body has the ability to repair itself. When the vascular endothelium is damaged, the body will mobilize platelets with hemostatic function to the damaged area to "put out the fire." This is the reason why there is a restenosis rate of about 10% after stent placement. The effect of aspirin is to prevent platelet aggregation. You can take 75 to 300 mg a day (the specific amount should be determined by your doctor). This medicine is very cheap, costing only a dozen yuan a month.

What are the contraindications for stent surgery for coronary heart disease? Patients who have undergone stent surgery tend to go to two extremes. One is that they feel that the disease has been cured and exercise frantically; the other is that they always think that there is a "wire ring" in their heart, so they are cautious in everything and basically do not exercise. After stent surgery, patients should have an "exercise prescription". The general principle is that activities should be gradual, from light workload to normal working state. The maximum workload should not exceed 70%~80% of the preoperative workload. You can persist in swimming, walking, jogging, cycling, Tai Chi, etc.
